It is important that most of the fresh water remaining from the last flush is dumped before the reject hose
is led in the cleaning bucket for re-circulation in order to avoid diluting the solution.
Use cleaning chemical #1 first. Only if the performance does not improve, use the acid cleaner #2 at the
same ratio and instruction.
MAINTENANCE TIMETABLE
The following maintenance timetable is an estimate of the time intervals at which maintenance may be
required only. This schedule must be adjusted to the regularity of usage, the condition of the intake water,
the length of time the system is exposed to seawater and the total running time following each system
cleaning.
